Denis Shapovalov is one to watch despite US Open fourth round loss
Tennis has been patiently waiting for a new generation to emerge and, despite losing his fourth round at the US Open, Denis Shapovalov has barged his way into its vanguard.
The 18-year-old lefthander was trying to become the youngest Grand Slam quarter finalist since Michael Chang in 1990 when he walked onto the Arthur Ashe Stadium, its roof pulled over due to further bad weather.
In the end he could not summon up sufficient composure at the big moments and fell 7-6, 7-6, 7-6 to the far more experienced number twelve seed Pablo Carreno Busta, who became the first man through to the last eight.
Yet Shapovalov, virtually unknown until the Davis Cup incident against Great Britain when he accidentally fired a ball into the umpire's eye, has won a legion of admirers here, and with a bit more sangfroid could have won all three sets.
The 18-year-old has been marked as one of the sport's brightest upcoming talents
Drawing comparisons with Roger Federer and Rafael Nadal at the same age from the likes of Mats Wilander, this will certainly be the last time that he has to qualify for a Major, as he was made to do here.
His slight lack of courtcraft was exposed in all three tiebreaks, which he lost in a sequence of 7-2 7-4 7-3 but it is significant that there have been two teenagers in the fourth round, the other being Russian Andrey Rublev.
Spain's underrated Carreno-Busta was left awaiting the winner of Frenchman Lucas Pouille and Argentina's diminutive Diego Schwartzmann.
